The definition of "sect" does not categorially include the definition of heretical. A sect is defined as a group of people forming a distinct unit within a larger group. It's where we get the word "section" from.
Examples:
Orthodox Jews are a sect of Judaism. Presbyterians are a sect of Reformed Christians. Calvinists are a sect of Protestants. Bostonians area sect of New Englanders. IFB's are a sect of Baptists. Calvareans are a sect of the Jesus Movement. Sometimes religious sects are demoninational, sometimes they're not.
Your definition is accurate to a point. Why not accept what the definition of the word "sect" actually means? This little banter reminds me of the present administration in the White House that says something and then redefines when it is challenged. Here are some "authoritative" definitions of the word "sect."

The historical usage of the term sect in Christendom has had pejorative connotations, referring to a group or movement with heretical beliefs or practices that deviate from those of groups considered orthodox.[1] [Emphasis added.]
1 Wilson, Bryan Religion in Sociological Perspective 1982, ISBN 0-19-826664-2 Oxford University Press page 89. "In English, it is a term that designates a religiously separated group, but in its historical usage in Christendom it carried a distinctly pejorative connotation. A sect was a movement committed to heretical beliefs and often to ritual acts and practices like isolation that departed from orthodox religious procedures."
It is my belief that the usage of the word "sect" in the exchange of these forum posts is the one that defines it as an heretical group. I know I cannot discern the intended definition used by the people who said the KJVO people are a sect, but my guess, in light of the contemporary view and debate of those who hold the position and the attempt to connect them with Peter Ruckman would define the word in the way indicated above, an heretical group. This has been the methodology of all who "violently" oppose the KJVO position.
Sometimes the truth is hard to accept. Does any more need to be said about this matter? P.S. Please read the whole post above and not just the parts you agree with. JR
